What are some bdsm-related and/or erotic films?

I am talking about films that ARE NOT pornographic. For instance I
like the movie: The Girl(about lesbians). Then there is the movie
Chloe..

Basically I want to see a movie about bdsm related and or erotic
topics...twisted...passionate, unhealthy love affairs.

I know its weird lol but I like me.

Thanks.
also nothing violent.
